摘要
采用高温熔融直接发泡制备钼渣多孔玻璃,通过研究不同发泡剂对钼渣多孔玻璃性能的影响,确定最佳发泡剂,研究了最佳发泡剂含量对钼渣多孔玻璃气孔率和抗折强度的影响。结果表明,BaCO3在本体系中发泡效果最好,随着发泡剂BaCO3含量的增加,钼渣多孔玻璃气孔率和抗折强度均发生变化,当BaCO3含量10%wt时,气孔率最高,为16.8%。X射线衍射分析钼渣多孔玻璃有少量石英残留,显微结构表明孔结构基本上不连通,为闭孔材料。
The porous glasses of molybdic tailing were prepared by melt quenching methods.By investigating influence of different pore-forming agents on the properties of porous glass of molybdic tailing, the optimal pore-forming agent was determined.The influence of the content of optimal pore-forming agent on the porosity and bending strength of porous glass of molybdic tailing were analyzed. The results showed that BaCO3 in this system was the best pore-forming agent, the porosity and bending strength of porous glass of molybdic tailing both were changed with the increase of the content of BaCO3, and the highest porosity is 16.8% when the content of BaCO3 attained 10%. It was found that a small amount of quartz was residue in porous glass of molybdic tailing by XRD techniques, and the pore structure was not connected on the whole, it was closed-cell material.
